Pause in 'for' loop with opportunity to work with other windows

Hi all,

Is there possibility to make a pause in 'for' loop with the opportunity to work with other windows within Igor Pro? I tried to use DoAlert, but this command doesn't allow to perform actions in other windows. For example, I have a data set of 20 experimental graphs. I use loop for(i=0; i<numItems; i+=1). First, i = 0, display graph, then pause to allow me to perform manual fitting in selected range using specified panel with a number of buttons. Second, i = 1, display graph, then pause to do fitting, and so on. How can I implement it?

Here is the main function:

Function Fit_Semilog()
	DoWindow/F FittingPanel
	if (V_Flag != 0)
		return 0
	endif
		
	NewPanel /N=FittingPanel /K=1 /W=(316,379,680,700) as "Fitting Panel"
	Button FitInFullRange,pos={30.00,20.00},size={300.00,20.00},proc=FitInFullRangeProc,title="Fit in full range"
	Button Show_Info,pos={30.00,50.00},size={300.00,20.00},proc=Show_InfoProc,title="Show Info"
	Button Hide_Info,pos={30.00,80.00},size={300.00,20.00},proc=Hide_InfoProc,title="Hide Info"
	Button FitInSelectedRange,pos={30.00,110.00},size={300.00,20.00},proc=FitInSelectedRangeProc,title="Fit in selected range"
	Button SubtractFitValFromFirstPart,pos={30.00,140.00},size={300.00,20.00},proc=SubtractFitValFromFirstPartProc,title="SubtractFitValFromFirstPart"
	Button RemoveFitFromGraph,pos={30.00,170.00},size={300.00,20.00},proc=RemoveFitFromGraphProc,title="Remove fit from Graph"
	Button TryAgain,pos={30.00,200.00},size={300.00,20.00},proc=TryAgainProc,title="Try again"
	Button SaveGraph,pos={30.00,230.00},size={300.00,20.00},proc=SaveGraphProc,title="Save Graph"
	Button Continue_,pos={30.00,260.00},size={300.00,20.00},proc=Continue_Proc,title="Continue"
	
	String listX = WaveList("*Time",";","")
	String listY = WaveList("*Int",";","")
	Variable numItems = ItemsInList(listY)
	Variable i
	String nameY, nameX
	for (i=0; i<numItems; i+=1)
		nameX = StringFromList(i,listX)
		nameY = StringFromList(i,listY)
		Wave wX = $nameX
		Wave wY = $nameY
		Display wY vs wX
		ModifyGraph mode=3,marker=19,msize=1,rgb=(0,0,65535)
		
		Display wY vs wX
		ModifyGraph mode=3,marker=19,msize=1,rgb=(0,0,65535)
		
		Display wY vs wX
		ModifyGraph mode=3,marker=19,msize=1,rgb=(0,0,65535)
		// Here should be a pause with opportunity to work with other windows
	endfor
End

macro FitSemilog()
	Fit_semilog()
end
